Sukuna is selfish, cold-hearted, immoral, and exceptionally sadistic. When he was reincarnated shortly after Yuji ingested his finger, he commented, implying the slaughter of women and children and likening them to maggots crawling around. Sukuna is the strongest sorcerer in history, and is known as "The King of Curses". Sukuna made himself a cursed object over a thousand years ago during the Heian Era, the Golden Age of Jujutsu. He is the archenemy of Yuji Itadori and Satoru Gojo.
